Yes, because when you add the squares of the two sides it equals 16, which is the square root of four

Answer:

yes

Step-by-step explanation:

the Pythagorean Theorem states that

a^2+b^2=c^2

or to me more specific the two shorter side lengths squared added together equal the hypotenuse squared

So basically what im saying is that if this is a right triangle then

4^2=\sqrt{6} ^2+\sqrt{10} ^2

4^2=16\\\sqrt{6} ^2=6\\\sqrt{10}^2=10\\10+6=16\\16=16

The following statement is true therefore it is a right triangle :)

madreJ [45]

Answer:

A

Step-by-step explanation:

A is an arithmetic sequence with first term -2 and common difference 5.  Each new term is found by adding 5 to the previous term.

B is a geometric sequence with first term 1 and common ratio 1/2.

C is neither an arithmetic nor a geometric sequence.

D is neither.  We might call it an "alternating sequence."

Eden just bought a trough in the shape of a rectangular prism for her horses. She needs to know what volume of water to add to t
notsponge [240]

The volume of the trough is V(w) = w³ + 20w² - 429w and the rate of change of the volume over a width of 38 inches to 53 inches is 4695 in³/in

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more variables and numbers.

Let w represent the width, hence:

length = w + 33, height = w - 13

Volume (V) = w(w + 33)(w - 13) = w³ + 20w² - 429w

V(w) = w³ + 20w² - 429w

Rate of change = dV/dw = 3w² + 40w - 429

When w = 38, dV/dw = 3(38)² + 40(38) - 429 = 5423

When w = 53, dV/dw = 3(53)² + 40(53) - 429 = 10118

Rate = 10118 - 5423 = 4695 in³/in

The volume of the trough is V(w) = w³ + 20w² - 429w and the rate of change of the volume over a width of 38 inches to 53 inches is 4695 in³/in
